I 1 shoes. However, it is to be understood that the r 'The fastening-pulling machine shown in the v 5 invention is not limited to use inconnection with illustrated embodiment of the invention comprises co machines for pulling staples but is adapted. to an oscillatory fastening-pulling tool in the form other uses such as, for example, in connection of a claw 10 having at its end portion a plurality with machines for pulling upper tacks from shoes. of narrow pointed teeth 12 (Figs. 1 and 3 each It is an object of the invention to provide an of which is adapted for insertion beneath the cross 10 improved fastening-pulling machine which will bar of a fastening such as one of the staples 14 5 be especially adapted to use in pulling temporary driven throughthe upper 16 and anchored inthe fastenings fromshoes such as, for example, shoes insole 18 ofjafla'sted shoe 20. The claw 10 is in which the upper and insole'are permanently carried at the outer end of a lever 22 mcuntedforsecured together bycement, and in which staples oscillation relatively to the frame-2i of the ma.- are employed to secure the upper to the insole in china. The central portion of the lever 22 is 70 lasted positionwhile the cement is setting. To secured to a rock shaft 26 mounted in theframe this end, and as illustrated, the invention proand having a crank arm 28 which carries a crankvides a fastening-pulling machine comprising an pin 30 upon which the lever is'held' by a disk 32 oscillatory tool, gage member's positioned beyond and a studB. The inner end of thelever 22 is opposite'ends of a portion'of the path of the tool operatively' connected to a drive shaft 36 by 7 for locating in a direction transverse'to said poi,- means of a crank 38 secured to the shaft and havtion of the path a fastening in a shoe presented ing a crank pin 40 upon which the end of the V to the gage members, and a gage member for em lever 22 is mounted and is secured thereto by a gaging the side of the shoe for locating the washer 42 and a nut 44. The drive shaft 3 6, fastening along the path in position to be pulled through the crank 38,"imparts to the lever 22 an 0 by the tool. Preferably the tool is in the form of oscillatory movement which is modified'by the a claw arranged to move inwardly over'the margin rocking of the shaft 26 with the result that the of the upper throughout the pulling portion of claw 10 at the outer end of the lever 22 isgiven its path, two of'the gage members being located a movement in a closed path somewhat elliptical to engagea shoe upon opposite sides Ora line of in shape as shown by dotted lines indicated by fastenings therein firmly to support the shoe reference character '46 in Fig. 2.

The gage member 50 is secured to Fig. 1 illustrates a side view of a portionvrof a the extension 56 by screwsfill extending through machine embodying one. form of the'inv'ention; elongated slots 62 in the member 50 and into Fig. 2 illustratesdetails ofthefastening-pulling the extension 56. This construction provides for r i- ,L vertical adjustment of the gage for locating the inner portion of the shoe in a direction transverse to or heightwise of the path of movement of the claw.

The gage member 52 is mounted in a slot 64 in a lateral projection 66 in the extension 56 and has a downwardly and inwardly curved portion 67. The gage member 52 can be adjusted vertically and can be locked in adjusted position by means of a screw 68 extending through an elongated slot 70 in the gage and into the projection 66. The gage 52 acts as a guard to prevent injury to the work; or to the operator by the claw 10, and in the operation of the machine the inwardly curved end 67 of the gage makes contact with the inturned marginal portion'of the upper to provide a work support which, in connection with the gage member 50 on the other side of the line of staples, limits upward movement of a shoe presented to the gages and thereby locates staples to be pulled at such position transverse to or heightwise of the path of movement of the claw 10 that the'cross bars of the staples, such as partially driven staples 14, are located slightly above the lowermost point of the path of the claw 10.

The gage member 54 comprises a shank 72 secured to the outer portion of the extension 56 by a screw 74 and by a screw '76 extending through a curved slot 78 in the gage member. The lower end of the gage member 54 is provided with a vertically extending, slightly curved surface 80 adapted to engage the side portion of a shoe presented to the machine and toguide the shoe in such manner as to present a line of fastenings 14 along the margin thereof substantially at right angles to the path of movement of the claw. Adjustment of the'gage member 54 outwardly or inwardly of the claw is attained by loosening the screws 74 and '78 and rocking the the'fastenings in predetermined positions relatively to the path of the claw 10. As illustrated in Figs-2 and 3, a portion of the shoeZO has an upper 16 the marginal portion of which is lasted overthe insole 18 and secured thereto by partially driven clinched staples 14 which, in practice and as shown,. are located in a line along the margin of the upper at a substantially constant distance from the side of the shoe. It is to be noted that the side of the shoe 20 is shown in engagement with the face 80 of the gage member 54 which is adjusted longitudinally of the claw in position to locate the line of staples substantially along the lowermost portion or the path of the claw which is shown about to engage a staple beneath the cross bar thereof. The gage member 52 engages the marginal portion of the upper upon one side of the line of staples and the gage 50 engages the insole 18 on the other side of the line of the staples, thus firmly to support the shoe in operative position heightwise of the pulling portion of the path of the claw 10 with the cross bars of the staples located slightly above the lowermost portion of the path in positi'onto be engaged by one of the teeth 12 when the staples are brought into the path of the claw.

all

, as shoe 20, is presented bottom-up to the gage members 50 and 52 which engage the'bottom of the shoe on opposite sides of the line of staples 14 and locate the shoe heightwise of the path of the pulling claw 10 with the cross bars of the staples extending slightly above the lowermost portion of the path of the claw. The shoe is held outwardly of the claw against the gage member 54 and is then advanced substantially at right angles to the path of movement of the claw so guided by the gage member 54 that the staples are directed into the pulling portion of the path thereof. The claw, which is oscillated, operates topull the staples as the shoe is advanced. Since the claw in pulling a staple operates from the outer portion of the-shoe inwardly over the upper and since the gage members prevent movement of the shoe into the path of the claw, likelihood of injuring the shoe is avoided. It is to be noted that in its effective or pulling position of its path the claw follows a path which is substantially a continuation of thecurve of the clinched portion of. the staple with the result that staples can be pulled'with' a minimum of resistance, thus avoiding any likelihood of injuring the upper of the shoe as the clinched portion of the staple is withdrawn therefrom.
